If you live in Brazil you have certainly had a conversation about the meat scandal that made the news last Friday. It stands to reason that students will have conversations about the same topic if they work for multinational companies or if they have foreign friends.
With that in mind, I choose this topic to provide students with vocabulary to talk about this topic in English. This is aimed at adult students who are B2 or C1. You may need to adapt the text further or pre-teach more vocabulary if you want to use it with B1 students.
